Interference Statement
FCC Part 15
This equipment has been tested and found to comply with the limits for a Class B digital device,
pursuant to Part 15 of FCC Rules. These limits are designed to provide reasonable protection
against harmful interference in a residential installation. This equipment generates, uses, and can
radiate radio frequency energy and, if not installed and used in accordance with the instructions,
may cause harmful interference to radio communications. However, there is no guarantee that
interference will not occur in a particular installation. If this equipment does cause harmful
interference to radio or television reception, which can be determined by turning the equipment off
and on, the user is encouraged to try to correct the interference by one or more of the following
measures:
1. Reorient or relocate the receiving antenna.
2. Increase the separation between the equipment and receiver.
3. Connect the equipment into an outlet on a circuit different from that to which the receiver is
connected.
4. Consult the dealer or an experienced radio technician for help.
FCC Caution
This equipment must be installed and operated in accordance with provided instructions and a
minimum 20 cm spacing must be provided between computer mounted antenna and person’s body
(excluding extremities of hands, wrist and feet) during wireless modes of operation.
This device complies with Part 15 of the FCC Rules. Operation is subject to the following two
conditions: (1) this device may not cause harmful interference, and (2) this device must accept any

z Main Chipset Specification
MAC/Baseband Processor
The RT2880 SOC combines Ralink’s 802.11n draft compliant 2T3R MAC/BBP,
a high performance 266-MHz MIPS4KEc CPU core, a Gigabit Ethernet MAC
and a PCI host/device, to enable a multitude of high performance,
cost-effective 802.11n applications. The RT2880 has two RF companion
chips, the RT2820 for 2.4G-band operation and the RT2850 for dual band
2.4G or 5G operation. In addition to the traditional AP/router
application, the chipset can be implemented as an WLAN “intelligent”
NIC, drastically reducing the load on the host SOC, such as DSL/Cable
or Multimedia Applications processors. Users can treat the WLAN iNIC
as a simple Ethernet device for easy porting and guaranteed 802.11n WLAN
performance without the need to upgrade to an expensive host SOC.

11b/g/n Transceiver
RT2820 is a monolithic SiGe RF IC that integrates multiple half-duplex
direct-conversion radio transceivers designed for IEEE802.11b/g/n WLAN
systems or other wireless LAN applications operating in 2.4GHz ISM bands.
The IC has two concurrent transmit channels and three concurrent receive
channels. The multiple channels are designed to improve robustness and
throughput during wireless operation. Each receive channel achieves low
noise figure, high input sensitivity, high linearity, and high output
power while consuming low DC power. Each receive path features a gain
selectable, low-noise amplifiers (LNA), followed by RF-to-baseband I/Q
demodulators, discrete-step variable-gain amplifiers and integrated
channel-selection filters. The transmit chain includes integrated
reconstruction filters, a baseband-to-RF I/Q modulator, discrete-step
variable-gain amplifiers for power-level control, and pre-drivers for
external power amplifiers. The modulator and demodulator are driven by
internal VCO. The VCO is phase-locked by an internal 3-wire-interface
PLL. The bandwidth of the integrated channel-selection filters and the
reconstruction filters can be programmed to narrow-band (10MHz) and
wide- band (20MHz). Their bandwidth is calibrated by an internal
autonomous calibration circuit. To help IQ mismatch calibration, a
baseband transmit-to-receive loopback feature is provided. A crystal
oscillator using external crystal and three low dropout regulators (LDO)
are also integrated. The RT2820 is housed in a 76-pin 9x9mm2 leadless
QFN package and is well suited for PCMCIA, MiniPCI, PCI, USB boards or
embedded applications. It is designed to work seamlessly with RT2860B
and RT2880 baseband/Mac IC.
